It seem to happen when I setup an alpha channel in the nodes area. I´ve tried to do it on another video and it happens no matter what. I´ve checked with different tutorials online and no of them get these squares at the bottom.

I´m working on a deadline for Monday so help is much appreciated.

What do you mean by "setup an alpha channel in the nodes area"? Are you adding an alpha output to your correction? Is it a timeline correction or on individual clips?

Strangely, it looks a bit like the Color Palette OFX ... Maybe somehow it made its way to your node structure? Maybe on a timeline or group correction?

Uli, this model has also a strong Radeon Pro 560 with 4 g... It runs Resolve flawlessly

I also found several other big bugs in the green screen department with this program and I have recorded them with a screen capture. Anyone know where to send these?

Happy you solved this very strange problem... Not sure about the "sucky" part though... More like an exotic and extremely rare, currently documented once and still not duplicate-able bug

As a side note. Resolve's Qualifiers are not initially made for green screen work. What qualifier did you use to key? If you really have to do this in Resolve (as opposed to Fusion), you should use the 3D Keyer, with the Despill box ticked and key inverted. With proper Matte Finesse work it gives the best results
